SaaS development cost. Stage by stage.
What you pay tracks your revenue stage: MVP, post-PMF, scale, or enterprise. Each stage needs its own mix of multi-tenancy, billing, auth, compliance, and observability. We also hand you the build-vs-buy math that decides which features earn custom code.

- A SaaS MVP that takes a customer payment costs $30,000-$80,000.
- Scale-stage SaaS (multi-tenancy, SSO, SOC 2, admin dashboard) runs $200,000-$500,000; enterprise multi-region crosses $1M.
- Cost is driven by the revenue stage you build for. Over-building at MVP and under-building at scale are the two costly mistakes.
- The biggest lever is build-vs-buy: custom auth is six weeks, Clerk/WorkOS is a day. Build the core, buy everything else.
- We give a stage assessment, a build-vs-buy recommendation, and a fixed-fee scope inside two business days.
$30K to $1M+. Stage decides everything.
A SaaS MVP that takes a customer payment costs $30,000 to $80,000. A scale-stage SaaS with multi-tenancy, SSO, SOC 2 compliance, and an admin dashboard runs $200,000 to $500,000. Enterprise SaaS with multi-region deployment and customer-specific integrations crosses $1M.
What moves the number is the revenue stage you build for. Over-building at MVP and under-building at scale are the two most expensive mistakes.
Four stages. Four right architectures.
Build for the stage you are at, not the one you imagine. Timing is the whole game. Adding multi-tenancy at MVP takes a week. Adding it at $5M ARR is a 2-3 month migration. SOC 2 runs the other way: wasted budget at MVP, table stakes for enterprise deals at $2M ARR.
| stage | scope | timeline | market range |
|---|---|---|---|
| MVP / pre-PMF | 5-10 features, Stripe billing, basic auth, single-tenant DB | 10-16 weeks | $30K-$80K |
| Post-PMF | Multi-tenant DB, observability, support tooling, admin panel | 16-26 weeks | $80K-$200K |
| Scale | SOC 2, SSO (SAML / OIDC), advanced billing, RBAC, audit logs | 24-40 weeks | $200K-$500K |
| Enterprise | Multi-region, dedicated environments, custom integrations | 32-52 weeks | $500K-$1M+ |

Eight cost components. Add them up.
| component | MVP | scale-stage |
|---|---|---|
| Auth (login, signup, password reset) | $3K-$8K | $15K-$40K (with SSO) |
| Multi-tenancy | $5K-$15K (shared DB) | $30K-$80K (schema-per-tenant) |
| Billing + subscription | $5K-$12K (Stripe Checkout) | $25K-$80K (custom tiers, usage) |
| Core feature set (5-10 features) | $15K-$40K | $80K-$200K (deeper features) |
| Admin dashboard / support tooling | $2K-$8K | $25K-$60K |
| Observability + monitoring | $1K-$3K (Sentry + analytics) | $15K-$40K (Datadog + custom) |
| Compliance (SOC 2, HIPAA) | Skip at MVP | $40K-$120K (one-time) |
| Design + UX system | $8K-$20K | $40K-$120K (full design system) |
Components compound. A scale-stage SaaS with all 8 lands at $270K-$740K. Skipping observability at MVP is fine. Skipping it at $1M ARR means flying blind through every customer incident.
Buy these. Build only what differentiates.
The single biggest cost lever in SaaS development is what you build versus what you buy. Custom auth is six weeks of engineering. WorkOS or Clerk is a day. Custom billing is months. Stripe Billing is a week. Build the core product. Buy everything else.
| capability | buy this | cost saved |
|---|---|---|
| Authentication + SSO | Clerk, WorkOS, Auth0, Supabase Auth | $30K-$70K |
| Billing + subscriptions | Stripe Billing, Paddle, Lago | $40K-$100K |
| Email transactional | Resend, Postmark, SendGrid | $15K-$40K |
| Customer support / chat | Intercom, Plain, Help Scout | $20K-$60K |
| Analytics + product analytics | PostHog, Mixpanel, Amplitude | $25K-$80K |
| Search | Algolia, Meilisearch, Typesense | $20K-$60K |
Buying these six saves $150K-$410K on a typical scale-stage build. The trade-off is monthly per-user cost ($500-$5K/mo combined). That is almost always cheaper than the engineering payroll the alternatives require.
Year-one stack. Not in the build quote.
| item | MVP (1K users) | scale (50K users) |
|---|---|---|
| Hosting (Vercel / AWS / Render) | $50-$300/mo | $2K-$15K/mo |
| Database (Supabase / Neon / RDS) | $25-$200/mo | $500-$5K/mo |
| Auth (Clerk / WorkOS) | $0-$100/mo | $500-$3K/mo |
| Email + transactional | $20-$100/mo | $300-$2K/mo |
| Monitoring (Sentry / Datadog) | $0-$50/mo | $300-$3K/mo |
| SOC 2 audit (annual, scale-stage only) | N/A | $15K-$40K/year |
| Engineering retainer / iteration | $5K-$15K/mo | $25K-$80K/mo |
Recurring infra runs $100-$750/mo at MVP and $4K-$25K/mo at scale. The engineering retainer is the biggest line item. SaaS that does not iterate stagnates.
Six honest answers.
How much does it cost to build a SaaS MVP?
A SaaS MVP that takes a paying customer costs $30,000-$80,000 from a senior-led agency. That budget covers 5-10 core features, Stripe Checkout for billing, and basic auth through Clerk or Supabase Auth. You also get single-tenant or shared-DB multi-tenancy, a simple admin panel, and one or two integrations.
Expect a 10-16 week build. The biggest mistake here is over-engineering. Skip multi-region, SSO, SOC 2, and custom auth, and you save $50K-$150K while you ship and validate. See our SaaS MVP in 90 days playbook.
What does multi-tenant SaaS architecture cost?
It depends on which of three patterns you pick. A shared database with a tenant_id column on every row costs $5K-$15K to set up and works fine for fewer than 1K tenants. This is the lowest-cost infrastructure option.
Schema-per-tenant uses a separate Postgres schema per customer and runs $30K-$80K. It scales to 10K tenants, but queries across tenants become harder to manage.
Database-per-tenant uses a separate database per customer, runs $80K-$250K, and provides full isolation. This is required for HIPAA and some enterprise deals, though it gets expensive to operate.
Pick by compliance requirements first, then by query patterns. We default to shared-DB at MVP and migrate to schema-per-tenant when the first enterprise prospect demands it.
How much does SOC 2 compliance add to SaaS development cost?
SOC 2 Type II readiness adds $40,000-$120,000 to the build, plus $15,000-$40,000/year for the audit itself. The build cost is engineering work: audit logs, RBAC, encryption at rest, vulnerability scanning, incident response runbooks. Use Vanta or Drata for continuous compliance ($1K-$3K/mo). They cut the audit prep time by 60-80%. Skip SOC 2 at MVP. You need it to unlock $50K+ ACV deals.
What's the cost difference between B2B and B2C SaaS?
B2B SaaS typically costs 1.5-2.5x B2C SaaS at the same revenue stage. The drivers are all enterprise plumbing: SSO + SAML / OIDC ($20K-$60K), team accounts and role-based permissions ($25K-$60K), audit logs ($10K-$30K), custom contracts and procurement integration ($15K-$40K), and SOC 2 readiness ($40K-$120K). B2C SaaS skips most of these. It spends instead on onboarding optimization, viral mechanics, and consumer-grade UX polish. The two markets have different cost shapes.
How long does it take to build a SaaS product?
An MVP that takes a paying customer needs 10-16 weeks. Post-PMF SaaS with multi-tenancy and observability: 16-26 weeks. Scale-stage with SOC 2 and SSO: 24-40 weeks. Enterprise SaaS with multi-region and dedicated environments: 32-52 weeks. Each stage assumes 2-4 senior engineers full-time. Faster builds (4-8 week MVP) exist, but they skip the hard parts: billing, auth, observability. All of that gets rebuilt before the first scale stage.
Should I build my own SaaS or use no-code tools?
No-code tools like Bubble, Webflow with Memberstack, and Glide work well for validation. You can ship a clickable product for $1K-$10K in just 2-4 weeks. But they break at scale.
Once you reach around 10K active users or need complex business logic, custom integrations, or real performance, custom code becomes necessary. Use no-code to validate demand. Move to custom development the moment you have paying customers and a roadmap that needs features no-code cannot deliver.
One warning: migrating from no-code to custom costs roughly as much as building from scratch. Don't over-invest in the no-code version.
